There are other factors,including
The temperature of object is higher than outside,it will emit radiation and become cool.
The temperature of object is lower than outside,it will emit radiation and become hot.
The rougher object is a better absorber and radiator.
The smoother object is a worse absorber and radiator.
The object which has bigger surface area emits or absorbs radiation faster.資料來源： my physical knowledge

The surface area and temperature of the object.
Objects with larger surface areas will emit/absorb thermal radiation more than those with smaller surface areas.
Also, the emission and absorption of thermal radiation by an object is proportional to the fourth power of its absolute temperature (Stefan's Law). That is to say, objects at higher temperature tend to emit radiation more than objects at low temperatures.
